If such configuration was used, the kernel would 12hang on “Waiting for root device” when booting from a microSD card. 13 14Signed-off-by: Grzegorz Szymaszek <gszymaszek@short.pl> 15Signed-off-by: Alexandre Torgue <alexandre.torgue@foss.st.com> 16Backported from: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/arch/arm/boot/dts/stm32mp157c-odyssey.dts?id=0171b07373cc8c2815ca5fa79a7308fdefa54ca4 17--- 18 arch/arm/boot/dts/stm32mp157c-odyssey.dts | 2 +- 19 1 file changed, 1 insertion(+), 1 deletion(-) 20 21diff --git a/arch/arm/boot/dts/stm32mp157c-odyssey.dts b/arch/arm/boot/dts/stm32mp157c-odyssey.dts 22index a7ffec8f1516..be1dd5e9e744 100644 23--- a/arch/arm/boot/dts/stm32mp157c-odyssey.dts 24+++ b/arch/arm/boot/dts/stm32mp157c-odyssey.dts 25@@ -64,7 +64,7 @@ &sdmmc1 { 26 pinctrl-0 = <&sdmmc1_b4_pins_a>; 27 pinctrl-1 = <&sdmmc1_b4_od_pins_a>; 28 pinctrl-2 = <&sdmmc1_b4_sleep_pins_a>; 29- cd-gpios = <&gpiob 7 (GPIO_ACTIVE_LOW | GPIO_PULL_UP)>; 30+ cd-gpios = <&gpioi 3 (GPIO_ACTIVE_LOW | GPIO_PULL_UP)>; 31 disable-wp; 32 st,neg-edge; 33 bus-width = <4>; 34-- 352.30.2 36 37
